GRAIN-DRILL P INT.

SPECIFICATION forming part of Letters Patent No. 252,148, dated January 10, 1882.

. Application filed May 7, 1881. (No model.)

To all whom it may concern:

Be it known that I, DANIEL J. shows, of Spruce Greek, Huntingdon county, and State of Pennsylvania, have invented a new and useful Grain-Drill Point, of which the following is a specification.

My invention relates to improvements on all grain and seed drills having boots of varying patterns, on which the point is usually riveted to the said boot, and to repair which or to sharpen the points the boots are commonly taken to a smithy, the rivets chipped loose, necessitating much labor and inconvenience before the sharpening can be attended to. Moreover, the points, after beingsharpened and riveted on again, are non-adjustable to vary the depth of deposit of seed, or to compensate for varying degrees of hardness of soil to secure uniform depth of insertion of the drill- .points; and hence the objects of my improvements are, first, to make the drill-point vertically adjustable by slotting it where the attaching-bolt passes through it to fasten it to the drill-boot, thus allowing it to be set at various heights on the said boot before it is clamped thereon by a suitable bolt and nut; second, to provide a drill-point, slotted as set forth, with similarpoints at both its ends to prolong the life of the device before it need be repaired, and so that its points may be reversed as occasion may require; third, to provide a peculiar head on theattaching-bolt for my improved drill-point, it being specially extended and thinned to avoid clogging by trash encountered by it; fourth, to provide a shield. washer with elongated body and with eye out of the middle thereof, to protect the slot in my drill-point from any objectionable matter that might lodge therein, and to make its body stronger. I attain these objects by the devices illustrated inthe accompanying drawings, in which--- Figure-l represents a drill-boot with my reversible point attached thereto with my improved bolt and adjusted to the maximum of shallow drilling. Fig. 2 represents the same adjusted to the maximum of deep drilling, the slot of the point being closed by my shieldwasher. Figs. 3, 4, and 5 represent respectively my reversible slotted point, my attaching-bolt, and my shield-washer.

Similar letters refer to similar parts throughout the several views.

A represents the drill-boot, a. b lugs thereon for drag-bars, and U a lug for the lift-chain.

13 represents my reversible drill-point, having its ends both pointed, and having the long slot D at its middle for stem of bolt to traverse it, that it may be adjusted vertically as the points wear or as the hardness of the soil may require.

Z is my attaching-bolt, having a wedge-form head, H, and shank It to receive a nut in the drill-tube.

N P is my shield-washer to cover the slot D of the point, as shown in Fig. 2. It has the eye X, as shown, out of its middle, that by reversing it may cover said slot in all positions after adjustment of the drill-point. Both it and the point may be reversed and adjusted by operating the bolt Z R by a wrench.

The operations and advantages of my drillpoints have most all been noted hereinbefore. I further explain that when drill-points are new and sharp the old way of attaching them is faulty, as they cannot be adjusted vertically to avoid too deep drilling. I overcome this difficulty readily without special pitch of the drag-bars, as is now sometimes done. Varying conditions of soil also require that they should be adjustable.

I am aware that reversible adjustable drillpoints are not new, as such, by passing the at- ,taching-bolt thereof through difl'erent holes in the front of the drill-boot, are quite old; also, that a long eye in the middle of a reversible drill-point for receiving snugly in it a long head of attaching-bolt of corresponding size and shape is also not new also, that new drillpoints are patented, which are made adjustable by reversing the points and securing them on the drill-boot peculiarly to resist wrenching action; but I am not awaretbat the eye or slot for attaching the drill by bolt has been made extra long to allow the point to be adj usted vertically without removal of said bolt by simply loosening it or its nut, which I therefore claim, though not broadly, in view of the foregoing.

What I regard as new and useful, and what I desire to secure by Letters Patent of the United States, is-

1. The reversible and adjustable drill-point In testimony that I claim the foregoing as [o B, having the extra long slotted eye D in its 'my'invention I have hereunto set; my hand and middle, and secured detaehahly to a drill-boot, seal.
